Integrating unmanned aerial systems and LSPIV for rapid, cost-effective stream gauging
Journal of Hydrology, 2018 Abstract Quantifying flow in rivers is fundamental to assessments of water supply, water quality, ecological conditions, hydrological responses to storm events, and geomorphological processes. Image-based surface velocity measurements have shown promise in extending the range of discharge conditions that can be measured in the field.

Velocity profiles and interface instability in a two-phase fluid: investigations using ultrasonic velocity profiler [PDF]
, 2018 In the present study the velocity profiles and the instability at the interface of a two phase water-oil fluid were investigated. The main aim of the research project was to investigate the instability mechanisms that can cause the failure of an oil ...

Steep Bedload‐laden Flows: Near‐Critical? [PDF]
, 2019 International audienceSteep gravel-bed rivers sometimes experience floods that dramatically rework river bed structure and topography. Hazard assessments and paleo-event reconstructions require better knowledge of such phenomena.
